MAX4527CSA+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4527CSA+ is a phase-reversal analog switch optimized for low-power applications. It operates from +4.5V to +36V single supply or ±4.5V to ±18V dual supplies. The device features an on-resistance of 175Ω maximum, matched between switches to 8Ω maximum. Leakage current is limited to 0.5nA at +25°C and 10nA at +85°C. Digital inputs have 0.8V to 2.4V logic thresholds for TTL/CMOS compatibility. Charge injection is 10pC maximum with 2pC matching. Transition time is 250ns maximum. It provides 2kV ESD protection per Method 3015.7 and handles rail-to-rail analog signals.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component designation includes the '+' suffix to confirm compliance with RoHS standards. Confirm the 'C' temperature grade corresponds to the required operating range of 0°C to +70°C. Ensure the package marking matches the 8-SOIC physical dimensions specified in the datasheet. Cross-reference the manufacturer date code against current production status to avoid obsolete stock.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part over the MAX4526 when lower power consumption is prioritized over high-speed switching performance. Verify that the application requires phase-reversal functionality rather than simple signal gating. Ensure the system voltage does not exceed the absolute maximum ratings of +44V total supply span. Check that the logic interface aligns with the specified 0.8V to 2.4V input threshold requirements.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4526/MAX4527 family of phase-reversal analog switches manufactured by Analog Devices Inc./Maxim Integrated. It shares the same analog characteristics as the MAX4526 but utilizes slower drivers for reduced current consumption. The device is designed for DC and low-frequency signal processing applications requiring precise symmetry and isolation.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct replacement options include the MAX4527CSA+. Verify pinout compatibility and electrical specifications before substitution. Other variants within the MAX4526/MAX4527 series may offer different temperature ranges or packaging options.
